IMPROVEMENT 'IN WASHING-MACHINES.

*HOLA- The Schedule referred to these Letters Patent and making -paxt ofthesame.

To all whom it may concern:

Be it known that I, L. Ii. MUHLINGHAUS, of Brook,- lyn, in the countyot' Kings, State of New York, havev invented a new and improved Washing-Machine; and I do hereby'deelare the following to be. a full,clear,'and exact description thereof', which will enable those skilledin the art to make -and use the same,

' reference being had lto the accompanying drawing,

forming part of this specification, in which drawing- Figure lrepresents a longitudinal vertical section of this invention.

Figure 2 is a transverse section of the same.v

Similar letters indicate corresponding parts.

I his invention relates to a washing-machine, which consists of aseini-cylilnlrical tub, hung on gudgeons, and provided with handles, andwith a closely-fitting cover, so that when the clothes to be washed andthe soap-suds have been introduced, and the cover is closed, the washingis eiiected by imparting to said tub an oscillating motion on itsgudgeons.

The operation of washing is facilitated by a series of round bars ortraverses, extending across the tub at a slight distance from its smoothconcave bottom, -in suchl a'manner, that the clothes,'by heilig causedto. rub against 'said traverses, are readily and quickly washed, and, atthe same time, by tilting the tubup, the water and soap-sudsl dischargewithout diliculty from the smooth bottom ofthe tub.y The sides of thetub are also corrugated.

In the drawing- The letter A designates a tub, which issemi-cylindrical, and niade of sheet-metal, or any other suitableinateiial.

The top of this tub is ilat, and it isprovided with an aperture, throughwhich the clothes to be washed and the water and soap-suds can beintroduced, and which can be hermeticallyLclosed by a cover, B, held inposition by a `rod or bridge, or by any other suitable ni'eaus, and soconstructed that it fits tight against packing-strips, secured to thesides in the aperture of the top, and that it prevents the water fromleaking out,when the tub is set in motion.

From the sides of the tubv project two gudgeons, a., which have theirbearings in standards b, rising from the frame O; and two handles c,extendingfrom 4the ends of the tub, serve'to impart to the sameanoscillating motion. v y

When it'is desired to retain the tub firmly in position, a pin, d, isintroduced through a-h'ole in onev of wood.

the standardsinto a socket orloop, c,fastene d to the bottom of saidtub, as shown in fig. 2.

. The sides ofthe tub are corrugated, the corrugai- Y tions beingproduced either in tbemetal from which the tub is made, or by' fasteningto the metal, strips of The concave bottoni of the tub is smooth, sothat when the tub is tilted up, the water and soap-suds will readilydischarge through the spoutj, which is closed by a plug or stop-cock.

In the interior of 'the tub, aud at a short dista-nce from its concavebottom, is secu-red -a sries of traverses, y, by preference made of Ycylindrical bars of w ood,and these traverses are placed at suitabledistances apart, so that when an oscillating motion is imparted to thetub, the clothes to be washed will pass with ajumping motion from onetraverse to the other, whereby the operation of washing is materiallyfacilitatedf Itwill be seen that the handles are secured to metal stripss, which extend longitudinally along the sides of the tub, and serve tostrengthen said tub.

The gudgeons a aresecured to these strips, so that the tub is notpierced or perforated, and thereby weakened.`

By placing the traverses at a certain distance from the bottom of thetub, the water and soap-snds are left free to discharge, when the tub istilted, and no trace of water remains, while with similar tubs havingcorrugated bottoms, it is diiiieult to discharge all the water, andsuchtubs are liable to corrode, by the water retained between the,corrugations I do not claim broadly, as my invention, a seini-cy-Ilindrical tub, hung on gudgeons, and so arranged thatan oscillatingmotion can be imparted to it'; but What I claim as new, and desire tosecure by Lett The construction and arrangement of the tub A,

ghaving its bottoni of a singlepiece of inet-al, with inl ternalcorrugated sides, andbraced bythe longitudi- Witnesses:
